Add a new patch to allow to build gcc 7.1 without extracting gcc/testsuite
directory.
This new gcc version require a kernel patch [1] to avoid a build issue with
____ilog2_NaN symbol. The following kernel version contain contain already
this patch :
4.11, 4.10.6, 4.9.18, 4.4.57, 3.18.50 and 3.12.73.
To build a toolchain based on gcc 7 and uClibc-ng 1.0.24, the patch [2] is
required to avoid a build issue due to missing aligned_alloc() definition.

+Subject: [PATCH] remove selftests
+
+When the gcc archive is extracted by the gcc.mk, the gcc/testsuite
+is excluded:
+
+HOST_GCC_EXCLUDES = \
+ libjava/* libgo/* \
+ gcc/testsuite/* libstdc++-v3/testsuite/*
+
+The new Makefile target from the "Selftest framework" [1] added a dependency
+on the gcc/testsuite/Makefile.
+Revert partially the commit [1] to allow building gcc without selftest.

-On glibc the libc.so carries a copy of the math function copysignl() but
-on uClibc math functions like copysignl() live in libm. Since libgcc_s
-contains unresolved symbols, any attempt to link against libgcc_s
-without explicitely specifying -lm fails, resulting in a broken

-Allow C99-depending features of libstdc++ with uClibc
-
-The libstdc++ code is fairly restrictive on how it checks for C99
-compatibility: it requires *complete* C99 support to enable certain
-features. For example, uClibc provides a good number of C99 features,
-but not C99 complex number support. For this reason, libstdc++
-completely disables many the standard C++ methods that can in fact
-work because uClibc provides the necessary functions.
-
-This patch is similar and highly inspired from
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
-a way that doesn't involve changing the configure.ac script, as
-autoreconfiguring gcc is complicated. It simply relies on the fact
-that uClibc defines the __UCLIBC__ definition.

-run. Add output messages to show the test result.
-* libiberty/configure: Regenerate.
-* libiberty/Makefile.in (install_to_libdir): Place the
-installation of the libiberty library in the same guard as that
-used for the headers to prevent it being installed unless
-requested via --enable-install-libiberty.

-libiberty: fix --enable-install-libiberty flag [PR 56780]
-
-Commit 199570 fixed the --disable-install-libiberty behavior, but it also
-added a bug where the enable path never works because the initial clear
-of target_header_dir wasn't deleted. So we end up initializing properly
-at the top only to reset it at the end all the time.

-Subject: [PATCH] xtensa: add -mauto-litpools option
-
-With support from assembler this option allows compiling huge functions,
-where single literal pool at the beginning of a function may not be
-reachable by L32R instructions at its end.
-
-Currently assembler --auto-litpools option cannot deal with literals
-used from multiple locations separated by more than 256 KBytes of code.
-Don't turn constants into literals, instead use MOVI instruction to load
-them into registers and let the assembler turn them into literals as
-necessary.
-
-2015-08-12 Max Filippov <jcmvbkbc@gmail.com>
-gcc/
- * config/xtensa/constraints.md (define_constraint "Y"): New
- constraint.
- * config/xtensa/elf.h (ASM_SPEC): Add m(no-)auto-litpools.
- * config/xtensa/linux.h (ASM_SPEC): Likewise.
- * config/xtensa/predicates.md (move_operand): Match constants
- and symbols in the presence of TARGET_AUTO_LITPOOLS.
- * config/xtensa/xtensa.c (xtensa_valid_move): Don't allow
- immediate references to TLS data.
- (xtensa_emit_move_sequence): Don't force constants to memory in
- the presence of TARGET_AUTO_LITPOOLS.
- (print_operand): Add 'y' format, same as default, but capable of
- printing SF mode constants as well.
- * config/xtensa/xtensa.md (movsi_internal, movhi_internal)
- (movsf_internal): Add movi pattern that loads literal.
- (movsf, movdf): Don't force constants to memory in the presence
- of TARGET_AUTO_LITPOOLS.
- (movdf_internal): Add 'Y' constraint.
- * config/xtensa/xtensa.opt (mauto-litpools): New option.

-
-Spilling windowed registers in userspace is much easier, more portable,
-less error-prone and equally effective as in kernel. Now that register
-spilling syscall is considered obsolete in the xtensa linux kernel
-replace it with CALL12 followed by series of ENTRY in libgcc.
-

- * config/xtensa/lib2funcs.S (__xtensa_libgcc_window_spill): Use
- CALL12 followed by series of ENTRY to spill windowed registers.
- (__xtensa_nonlocal_goto): Call __xtensa_libgcc_window_spill
- instead of making linux spill syscall.

-Subject: [PATCH 3/3] xtensa: fix _Unwind_GetCFA
-
-Returning context->cfa in _Unwind_GetCFA makes CFA point one stack frame
-higher than what was actually used by code at context->ra. This results
-in invalid CFA value in signal frames and premature unwinding completion
-in forced unwinding used by uClibc NPTL thread cancellation.
-Returning context->sp from _Unwind_GetCFA makes all CFA values valid and
-matching code that used them.

-Add musl support to gcc
-
-This patch comes from the musl-cross project at
-https://bitbucket.org/GregorR/musl-cross/src. Compared to the upstream version:
-
- * the config.sub modifications have been removed, because Buildroot
- already overwrites all config.sub with a more recent config.sub
- that has musl support.
-
- * change to ensure that a dummy dynamic linker path
- MUSL_DYNAMIC_LINKER<foo> is defined for all architectures,
- otherwise building gcc for architectures not supported by musl was
- causing build failure. Bug reported upstream at
- https://bitbucket.org/GregorR/musl-gcc-patches/issue/4/musl-gcc-patches-break-the-build-on.
-
- * change the USE_PT_GNU_EH_FRAME logic to keep the existing gcc logic
- and only add the musl one as an addition, not as a replacement. Not
- doing this breaks C++ exception handling with glibc, because
- USE_PT_GNU_EH_FRAME doesn't get defined due to the configure script
- not testing dl_iterate_phdr() on any system except Solaris.

Hello,
First of all, thanks for doing this work!
I've added Alexey, Waldemar and Vicente in Cc, since there are some
ARC, Microblaze, OpenRISC and MIPS questions below.

Nice to see that so many patches are upstream, and that our stack of
gcc patches for 7.x is now really small!
Perhaps we should start some effort to upstream the last few remaining
patches?

ARC is indeed still not supported fully in gcc 7.x I believe. Alexey,
do you confirm?
But what is the problem with Microblaze? And with OpenRISC? Waldemar?
OpenRISC has its own gcc version, so I guess that's the answer. But
what about Microblaze?

Vicente, what is the status of the support for those MIPS cores in gcc
7.x ?
Romain: I think we should also default to gcc 6.x now instead of
defaulting to gcc 5.x.
And perhaps we should start thinking about removing gcc 4.9.x as well.
For toolchain components, I don't think it makes sense to support more
than three versions, i.e:
1. old one (would be 5.x now)
2. default one (would be 6.x now)
3. bleeding edge one (would be 7.x now)
Thanks!
Thomas

There is a regression between gcc 5.x and 6.x for microblaze, which still prevents to bootup any system in qemu. (uclibc-ng, musl, glibc)
Problem is still present in gcc 7.
Does anyone have time to bisect it?
best regards
Waldemar

Well I'd say something completely opposite :)
GCC 7.x has as much of ARC support as it could be now. We submit all our changes
to gcc immediately and it's only a matter of review and approval delay for when it
lands in master branch of GCC. The same applies to GCC releases - whatever got merged
by the time of release is there. So I'd say we barely differ here a lot from other first
class citizens in GCC.
Moreover GCC 7.1 should work for us just fine and very limited amount of patches could
be needed to fix things here and there.
BTW and the same is true for Binutils. And frankly for quite some time now I was planning
to give upstream GCC/Binutils a try in Buildroot for ARC. So while we're on topic I guess
we may start from having 2 options for ARC users:
?* Build toolchain from ARC releases from GitHub forks of GCC and Binutils
?* Build toolchain from upstream releases

Indeed :)

I can add this in our TODO list for the next Buildroot summer camp or next meeting.

I haven't checked the status of all broken or unsupported architectures when
bumping to gcc 7. I wanted to keep the same dependency as gcc 6 for the moment.
